Nitrogen generators are the most widely used in the production industry, such as industrial production, glass production, nitrogen purging for silicon wafers in the electronics industry, and rigid demand in manufacturing industries. Nitrogen generators use air as raw material for compression and use carbon molecular sieves. High-performance adsorptive adsorption of nitrogen, direct production of nitrogen, is one of the most favorite equipment in the factory. Today, Xiaobian will explain it to you.
First, What is the role of the liquid nitrogen produced by the nitrogen generator?
1. The application of liquid nitrogen in animal husbandry includes the improvement of livestock freezing and preparation skills, the ultra-low temperature preservation of microorganisms in liquid nitrogen, and the long-term preservation of bacteria in liquid nitrogen at -196 °C. Its principle is to use microorganisms in -130 ℃ below the changing customs tend to be intermittent and effective preservation of microorganisms. There are also agricultural biological genes, vaccine preservation, and the use of liquid nitrogen to treat the closure of the outer opening of the milk nipple of dairy cows, and the skin tumors of livestock.
2. In fact, the application in medical work is a bit similar to the application in animal husbandry, but it is more complex and more diverse. Clinical hypothermia medicine is helpful for the development of transplant medicine. Necrosis, one way to achieve therapeutic goals, is a biochemical process.
3. In terms of food industry application, the application of liquid nitrogen in food quick-freezing is used in many preservation methods, and the cryopreservation method is widely used and has a very obvious effect. Compared with other freezing methods, liquid nitrogen quick freezing has fast freezing speed, maintains food quality, low material dry consumption, and low equipment and power costs, and is easy to complete mechanized and automated assembly lines to improve productivity. In addition, there is nitrogen in the beverages we drink. The traditional C02 is replaced by nitrogen or a mixture of nitrogen and C02, which makes the gas in the upper space of the storage tank lazy, and then prolongs the storage period of perishables. Storage and preservation of fruits, vegetables and meat products; low temperature damage is the process of breaking the material cooled to the embrittlement temperature into powder under the action of external force; it is used in food packaging and refrigerated transportation.

Second, Will the nitrogen generator be used in the metal cutting industry?
1. Scope of work
Oxygen-assisted combustion increases heat and increases the thickness of the incision. The advantage is low cost, and it is mainly used in carbon steel. Nitrogen does not assist combustion, and the temperature in the melting area is low, which is suitable for processing low melting point materials such as aluminum and brass. Nitrogen protects the slit from oxidation, and can also be used for oxidation-free cutting of stainless steel.
2. Cost
The price of high-purity nitrogen is three times that of high-purity oxygen. Oxygen cutting pressure requirements (1 ~ 4)*105Pa, nitrogen requirements (10 ~ 140*105Pa. For example, cutting a 2CM thick stainless steel plate, oxygen demand pressure 4*105Pa, gas consumption 2.3m3/h, nitrogen corresponds to It is 14*105Pa, 15.2m3/h. And nitrogen cutting requires high power, which increases energy consumption accordingly. The general cost of nitrogen cutting is more than 15 times that of oxygen cutting.
3. Open quality
According to the auxiliary gas used, laser cutting can be divided into two cutting methods: oxygen and nitrogen. In oxygen cutting, oxygen participates in combustion, and the melting temperature is close to the boiling point. The high temperature causes severe reaction and cannot ensure a smooth section; in addition, the oxidation reaction and the increased heat-affected zone make the incision quality relatively poor, and the quality of the incision width, cross-section twill, poor surface roughness and welding slag are easy to appear. shortcoming.
